Hi, I’m new to FirewallD so I am doubtful about initial setup.
does it work right after installation or do I have to do something?
there is an option: “Apply rules to interfaces:…” and neither option is selected, should I select eth0? (I use Virtualmin and Debian 9 only to Host Website)
why there is the “Save” link to Confirm this option? Was not it enough Apply Configuration?
Thanks in advance
